.To @135 whom it may concern.-

Be it known that I, JULIUS O. MILLER, a citizen of the United States,residing at Syracuse, in the county of Otoeand State of Nebraska, haveinvented a new and useful Inkstand, of which the following isaspecification.

This invention relates'to that class of inkstands which embody a dome orreservoir and feeding-cup and which have valve or air-inlet devices atthe top of the reservoir for controlling the admission of air to thelatter.

The object of my improvements is to provide a simple inkstand of thisclass which will possess advantages in the point of effectiveness,positive operation, ease of adjustment, durability, and generaleficiency.

In the drawings, Figure 1 is a perspective view of an inkstand embodyingmyimprovements. Fig. 2 is a vertical transverse sectional view of thesame. Fig. 3 is a detail transverse sectional view taken through thevalve devices at the top. Fig. at is a detail horizontal sectional viewtaken on the line 1 1, Fig. 3. Fig. 5 is a detail horizontal sectionalview taken on the line 2 2, Fig. 3. Fig. 6 is a detail perspective viewof the remov able cap-piece. Fig. 7 is adetail perspective view of thescrew-valve.

Referring to the drawings,A designates the body of the inkstand, whichis preferably formed of glass and comprises a flat base a, from whichrises the dome or reservoir a. The flat base preferably has an annularflange or shoulder a? on its bottom, which supports the inkstand andraises the base from the surface upon which the inkstand rests. The baseportion also preferably embodies an annular groove of, surrounding thedome or reservoir and forming an outside annular raised flange at,having its edge recessed or scalloped, as shown at or", to formsecuring-rests for pens or analogous articles. In the front face of thedome or reservoir is provided a vertical segmental concave recess a,- atthe base of which is provided an outwardly-projecting concave cup (1within the annular groove a and rising therefrom. Near the bottom ofthis cup and in the wall of the segmental concave recess a is formed afeed opening or perforation a through which the Serial No. 542,885. (Nomodel.)

ink is fed from the reservoir to the dippingcup.

The top of the reservoir is preferably approximately flat and isprovided with a central circular opening a, in which is permanently seta raised annular ring or flange 13, having a threaded opening I),surrounded by an annular edge Z), which is preferably inclined inwardlyor slightly concaved.

C designates the cap-piece of the valve mechanism, which comprises abody or main portion 0, exteriorly threaded, as at c, to correspond tothe threaded opening I), and a top portion 0 formiu g a flatcircumferential projecting flange 0 preferably having milled edge 0 tofacilitate the removal of the cappiece when desired. At the junction ofthe threaded portion c and the circumferential flange o the cap'piece isprovided with a circumferential groove or recess 0 in which is set anannular flexible or elastic washer-ring or packing D, the inner edge (Zof said ring being received within the circumferential groove 0 whilethe outer portion of the ring is tightly clamped against the inclined orconcaved annular edge I) by the circumferential flange 0 when thecap-piece is screwed down tightly into position, an air-tight jointbeing thus formed. From the top of the cappiece preferably projects anut-shaped head 0 adapted to facilitate the setting or adjustment of thecap-piece. The cap-piece is provided with a centralvertical bore 0 ofsuitable diameter and interiorly threaded, as shown at 0 the threadspreferably extending from a point a short distance above the bottom tonear the top of the bore. The bore has a bottom 0 in which is formed asmall eye or opening c opening into the reservoir and of a diameterconsiderably less than that of the bore. This improved cap-piece may, inits practical construction, have its main or body portion 0 and topportion 0 formed as a hollow cylindrical shell having a bottom 0 inwhich is formed the opening 0 and into this shell may be screwed or seta center piece embodying the nut-shaped head 0 and the bore 0', withbore portion resting tightly upon the bottom 0 and surrounding theopening 0 therein.

The construction just set forth is illustrated in the accompanyingdrawings, but it will be understood that the practical construction ofthe cap-piece to provide the es sential members or features hereindescribed may be varied as desired.

0 designates an air-inlet channel or opening extending from the top ofthe cap-piece into the bore 0 This channel is preferably formed by adiagonal perforation running from about the base of the nut-shaped headto a point near the bottom of the threaded portion of the bore 0 In thebottom of the bore is preferably set a Washer-block or bushing E,inwhich is also formed the opening 0 This bushing may be approximatelycup-shaped, and the bottontof the cappiece 0 may be correspondinglyformed, if desired, to neatly accommodate this bushing.

F designates the valve proper, which comprises a stem f and a projectinghead f, having a milled edge f The main portion of the stemfis threaded,as at f corresponding to the threaded bore. Below this threaded portionf the stem of the valve is reduced in diameter and is smooth, as shownat f, and from this smooth reduced portion projects a point f of lessdiameter, this point being adapted to be seated in the correspondingopening 0 The end of the point f is preferably of conical shape, asshown at f. The annular shoulder f formed by the bottom of the portion fof the stem, is adapted to be seated against or rest upon the bushing Ewhen the valve is closed.

It will be noted that my improved inkstand embodies in its top mechanismonly screwvalve devices, which insures a more effective operation,enables the more convenient and accurate adjustment or removal of thevalve devices, and obviates the use of spring or similar mechanisms,which are apt to become clogged or imperfect in operation as an airinletvalve.

The operation and advantages of my invention will be readily understood.The dome or reservoiris adapted to be effectively closed at the top bythe screw-valve mechanism, so that the ink is held in the reservoir bythe vacuum therein and is adapted to be fed to the dipping-cup by theadmission of air through thevaive. hen the screw-valve F is screwedtightly down, the reservoir is perfectly closed against the admission ofair. hen it is desired to admit air to the reservoir, the screwvalve Fis raised, so that the air in the bore surrounding the smooth reducedportion f of the stem of the Valve, which has been fed from theair-inlet 0 may pass into the reservoir.
